Repair Strategy
Reading operating error messages and the error log helps to determine whether a
fault is a hardware or software problem. Fault rectification is accomplished by
replacement of the defective part at the assembly level. For example, faults may
be repaired by replacement of a complete board where the fault is identified, or
by exchanging the monitor.
Repair or replacement of individual components on the boards is not supported,
and should never be attempted.
There are no servicing instructions in this manual for the Recorder (M2925A) as
a repair is effected by exchanging the unit only.
After any repairs you must carry out the following tests:
• Power-On Self-Test (see “FM-2 Power-On Self-Test” on page 20)
• Performance tests (see “Testing Transducers” on page 90)
• Safety tests after repair (see “Safety Testing” on page 84)
